IMPROVEMENT IN BEER-FAUCETS.

Specification forming part of Letters Patent No. 126,736, dated May 14, 1872.

SPEoIrrcATIoN.

I, LEOPOLD MULLENHOEF, of the city of Buffalo, in the county of Erie and State of New York, have invented certain Improve ments in Beer-Faucets, of which the following is a specification:

My improvements relateto that class of beerfaucets iu which a plug, made hollow at its lower end, is arranged in the end of and'at right angles, or nearly so, to the tube, which is inserted in the barrel or keg, so that the liquid from the said tube enters the plug through a hole therein and is discharged at the lower` hollow end thereof. The object of the invention is to so construct the parts that the plug, in addition to its ordinary function of a valve or stop-cock, may be made capable of being operated as a plunger 'when required to eject a limited quantity of the liquid with suiflcient force to produce the desiredfoaming of the liquid in the glass or mug. The invention consists, first, in the combination of the barrel of the faucet `with the hollow plungerplug, the bore at the lower end of the barrel beingl contracted, and the lower end of the plug correspondingly reduced in size by a rabbet so as to tand slide therein, so that when the plug is elevated thc liquid from the main tube will ilow into the annular space beneath the shoulder or rabbet and above theA contracted lower end of the barrel, and be ejected, by the descent of the plunger, through a small auxiliary passage with the required force for producing the desired foaming of the liquid; second, in the combination and arrangement of apertures in the shoulder or rabbet of the plunger-plug, closed by an annular valve, .and recesses in the plug above the said valve and rabbet, whereby the liquid from the main tube is permittedlto flow through the said apertures down into'the annular space, instead of entering said space around and beneath the rabbet, even when the plunger is only partiallyr elevated.

In the accompanying drawing, Figure I is a vertical section of my improved faucet, with theplu g in its normal and proper position when operating simply as a plug. Fig. II is a similar view with the plug elevated, showing the :manner in which the liquid enters the annular space of the barrel. Fig. III is a horizontal section in line x w, Fig. II. Fig. IV is a hori- Zontal section of the lower portion of the barrel in line y y, Fig. I, showing a bottom view ofthe perforated shoulder of the plug. Fig. V is a similar section in line z z. Fig. VI is a sectional view, showing the shoulder or jog in the plug unperforated.

Like-letters designate like parts in each of the iigures.

A is the main tube, which is driven or screwed into the vessel containing the liquid; and B, the barrelortube at its outer end, in which the plug and plunger G works. The plug is provided with a stem, c, which passes through a screw-cap, b, at the top of the barrel, which permits the plug to be turned, and also worked up and down. c1 are the ordinary holes through which the liquid is let into the plug, and c2 is the central passage in the plug throughwhich the liquid is discharged. d is the lower reduced portion of the plug, and d the shoulder or offset, formed at the point whence the rabbet commences. e is the contracted portion of the barrel, made to correspond with the portion cl of the plug; and e', a small vertical passage formed through the contracted portion e. The plug, above the rabbet or shoulder, is constructed with an annular space, f, with inletopenings fl in the outer shell thereof, and outletapertures f2 through the shoulder d', at the lower end. gis an annular valve, fitted on the under side ofthe shoulder d so as to close the apertures f2 when pressed upward.

i Operation.

When the plug is in position, shown in Fig. I, the liquid is discharged through the central passage c2 in an ordinary manner. By turning or pulling the plug upward the flow of the liquid through the plug is arrested. The plug being elevated, as shown in Fig. II, the liquid iiows from the tube A, through the openings f 1, into the annular space f, and thence through the apertures f2 into the annular space b left in the barrel below the offset d bythe elevation of the plug. By pressing' down on the plunger the valve gis closed, when the liquid confined in the space b is forced through the small passage e' into the glass or other receptacle. By the use of the valve g and annular4 space f a slight or partial elevation of the plunger Will cause the liquid to begin to ow tion d, in combination with the barrel B, prointo the space b. The employment of this vided With contracted end e and auxiliary pasvalve and annular space, although desirable, sage e', substantially as hereinbefore set forth. is7 however, not absolutely essential.
